2007-07-10[POWERPC] PS3: Bootwrapper support.Geoff Levand
Add support to build the PS3 flash rom image and remove some unneeded lmb calls. The PS3's lv1 loader supports loading gzipped binary images from flash rom to addr zero. The loader enters the image at addr 0x100. In this implementation a bootwrapper overlay is use to arrange for the kernel to be loaded to addr zero and to have a suitable bootwrapper entry at 0x100. To construct the rom image, 0x100 bytes from offset 0x100 in the kernel is copied to the bootwrapper symbol __system_reset_kernel. The 0x100 bytes at the bootwrapper symbol __system_reset_overlay is then copied to offset 0x100. At runtime the bootwrapper program copies the 0x100 bytes at __system_reset_kernel to addr 0x100. zImage.ps3 is a wrapped image that contains a flat device tree, an lv1 compatible entry point, and an optional initrd. otheros.bld is the gzip compresed rom image built from zImage.ps3. otheros.bld is suitable for programming into the PS3 boot flash memory.

2007-06-28[POWERPC] Make more OF-related bootwrapper functions available to non-OF ↵David Gibson
platforms Commit 2e6016133755eb3cc44e8efab92573d23ed75888 split up arch/powerpc/boot/of.c so that some OF functions can be used on platforms that don't want to use the overall OF platform boot code. This is useful on things like PReP which can have an OF implementation which is useful for debugging output, but inadequate for booting. However, that commit didn't export quite enough things to make a usable OF console on a non-OF system. In particular, the device tree manipulation performed to initialize the OF console code must explicitly use the OF device tree, rather than the flattened device tree, even if the system is otherwise booting using a flattened device tree.

2007-06-25[POWERPC] When appropriate, wrap device tree with zImageMark A. Greer
There are 2 config options that indicate whether the platform being built has a device tree source file associated with it. Namely, CONFIG_WANT_DEVICE_TREE and CONFIG_DEVICE_TREE. When CONFIG_WANT_DEVICE_TREE is 'y' and CONFIG_DEVICE_TREE isn't an empty string, automatically wrap the specified device tree with the zImage being built. To achieve this, the 'dts' variable will only be set when the conditions above are true. The changes to the zImage.initrd.% and zImage.% rules cause the device tree to be wrapped when 'dts' is set; otherwise, they will work as they previosly did (i.e., build a zImage with no device tree).

2007-06-14[POWERPC] Fix problems with device tree representation of TSI-1xx bridgesDavid Gibson
This fixes some problems with the way the some things represented in the device tree for the Holly and Taiga boards. This means changes both to the dts files, and to the code which instantiates the tsi108 ethernet platform devices based on the device tree. - First, and most importantly, the ethernet PHYs are given with an identical 'reg' property. This reg currently encodes the accessible register used to initiate mdio interaction with the PHYs, rather than a meaningful address on the parent bus (mdio in this case), which is incorrect. Instead we give the address of these registers as 'reg' in the mdio node itself, and encode the ID of each phy in their 'reg' propertyies. - Currently the platform device constructor enables a workaround in the tsi108 ethernet driver based on the compatible property of the PHY. This is incorrect, because the workaround in question is necessary due to the board's wiring of the PHY, not the model of PHY itself. This patch alters the constructor to instead enable the workaround based on a new special property in the PHY node. - The compatible properties on a number of nodes in the device tree are insufficiently precise. In particular the PHYs give only "bcm54xx", which is broken, since there are many bcm54xx PHY models, and they have differences which matter. The mdio had a compatible property of "tsi-ethernet" identical to the ethernet MAC nodes, which doesn't make sense. The ethernet, i2c, bridge and PCI nodes were given only as "tsi-*" which is somewhat inprecise, we replace with "tsi108-*" in the case of Taiga (which has a TSI108 bridge), and "tsi109-*", "tsi108-*" in the case of Holly (which has a TSI109 bridge). - We remove some "model" properties from the ethernets on Taiga board which were neither useful nor adequately precise. - On Holly we change to using a dtc label instead of a full path to reference the MPIC node, which makes the dts a little more readable.

2007-06-14[POWERPC] Don't store a command line in the Holly device treeDavid Gibson
Currently, the Holly device tree includes a bootargs property in /chosen, which gives a commandline. This is somewhat inconvenient, because it means an alternative default command line can't be given in the kernel config - the value obtained from the dts via the bootwrapper will always override CONFIG_CMDLINE. This removes the command line from the dts, and instead puts the same command line as a default in holly_defconfig.

2007-06-14[POWERPC] Consolidate cuboot initialization codeDavid Gibson
The various cuboot platforms (i.e. pre-device tree aware u-boot for 83xx, 85xx and Ebony) share a certain amount of code for parsing the boot parameters. To a certain extent that's inevitable, since they platforms have different definitions of the bd_t structure. However, with some macro work and a helper function, this patch improves the situation a bit. In the process, this fixes a bug on Ebony, which was incorrectly handling the parameters passed form u-boot for the command line (the bug was copied from 83xx and 85xx which have subsequently been fixed).

2007-06-14[POWERPC] Derive ebc ranges property from EBC registersDavid Gibson
In the device tree for Ebony, the 'ranges' property in the node for the EBC bridge shows the mappings from the chip select / address lines actually used for the EBC peripherals into the address space of the OPB. At present, these mappings are hardcoded in ebony.dts for the mappings set up by the OpenBIOS firmware when it configures the EBC bridge. This replaces the hardcoded mappings with code in the zImage to read the EBC configuration registers and create an appropriate ranges property based on them. This should make the zImage and kernel more robust to changes in firmware configuration. In particular, some of the Ebony's DIP switches can change the effective address of the Flash and other peripherals in OPB space. With this patch, the kernel will be able to cope with at least some of the possible variations.

2007-06-14[POWERPC] Split low-level OF-related bootloader code into separate filesDavid Gibson
Currently, all OF-related code in the bootloader is contained in of.c. of.c also provides the platform specific things necessary to boot on an OF platform. However, there are platforms (such as PReP) which can include an OF implementation, but are not bootable as pure OF systems. For use by such platforms, this patch splits out the low-level parts of the OF code (call_prom() and various wrappers thereof) into a new oflib.c file. In addition, the code related to bootwrapper console output via OF are moved to a new ofconsole.c file. Both these files are included in the wrapper.a library where they can be used by both full-OF and partial OF platforms.

2007-06-02[POWERPC] Don't use HOSTCFLAGS in BOOTCFLAGSDavid Gibson
In the bootwrapper code for powerpc, we include HOSTCFLAGS into the BOOTCFLAGS used for building the zImage wrapper code. Since the wrapper code is not host code, this makes no sense. This patch removes the use of HOSTCFLAGS here, instead including directly into BOOTCFLAGS those flags from the normal kernel CFLAGS which also make sense in the bootwrapper code. In particular, this makes the bootwrapper use -msoft-float, preventing the compiler from generating floating point instructions. Previously, under some circumstances the compiler could generate floating point instructions in the bootwrapper which would cause exceptions on embedded CPUS which don't have floating point support.

This patch corrects a number of minor errors in the Ebony device tree: - Missing (given as 0) cache sizes are added to the CPU node - device_type properties are removed from nodes which don't have a reasonably well defined device_type binding. This does require a very small code change to locate the busses to be probed for of_platform devices by 'compatible' instead of 'device_type'. - A node is added for the SRAM controller - The unit address of the small-flash node is adjusted to correctly reflect the reg property. - device_type values for the MAL and ZMII are updated to reflected more up-to-date versions of the binding. - An incorrect offset in the partition map for the large-flash node is corrected. - Some redundant values, already commented out are removed entirely.

2007-05-17[POWERPC] Fix bug adding properties with flatdevtree.c's ft_set_prop()David Gibson
ft_set_prop() from flatdevtree.c in the zImage wrapper will either replace an existing property in the flat device tree, or add a new property definiion if the given property isn't present. However, when adding properties, it adds the property definition immediately before the node's END_NODE tag, potentially after any subnode definitions for the node. This confuses the kernel flat tree parser in prom.c which assumes that all property definitions for a node come before all subnode definitions. This patch corrects ft_set_prop() so that it adds new properties before the first subnode, instead of before the END_NODE tag.

2007-05-12[POWERPC] Add bootwrapper support for Motorola PrPMC2800 platformMark A. Greer
The Motorola PrPMC280 and PrPMC2800 processor modules sit on an F101 or PrPMC2800 baseboard, respectively. There are several variants of each type of processor module which can have different amounts of memory, amounts of FLASH, cpu frequencies, and an mv64360 or an mv64362. The bootwrapper code for that platform reads VPD from an I2C EEPROM to determine the processor module variant. From the variant, the amount of memory, etc. is determined and the device tree is updated accordingly. If the variant cannot be determined (e.g., corrupted VPD or a previously unknown variant), the property values already in the device tree are used. Also, the firmware for those platforms does not completely configure the mv64x60 host bridge so that configuration is done here. Signed-off-by: Mark A.

Some platforms support a variety processor modules with no method of determining which exact processor module is being used except by examining Vital Product Data (VPD). The modules may have different amounts of memory, clock frequencies, etc. so reading the VPD becomes necessary to correctly set properties in the device tree before its passed to the kernel. Often the VPD is stored in I2C EEPROMs so an I2C driver becomes necessary. This I2C driver is for the I2C controller that's embedded on the Marvel mv64x60 line of host bridges. Signed-off-by: Mark A.

2007-05-12[POWERPC] Add bootwrapper support for Marvell/mv64x60 hostbridgeMark A. Greer
The mv64x60 host bridge has many windows between its various components (cpu, system memory, ethernet ctlr, MPSC, DMA ctlr, PCI MEM, PCI I/O). Unfortunately, the firmware on some of mv64x60-based platforms do not properly or completely configure those windows (e.g., MPSC->system memory windows not configured or CPU->PCI MEM space not configured). So, the missing configuration needs to be done in either the bootwrapper or in the kernel. To keep the kernel as clean as possible, it is done in the bootwrapper. Note that I/O controller configuration is NOT being done, its only the windows to allow the I/O controllers and other components to access memory, etc. that is being done--drivers assume that their controllers can already access system memory).

2007-05-12[POWERPC] Add Makefile rules to wrap dts file in zImageMark A. Greer
Add 'zImage.dts' and 'zImage.dts_initrd' build rules that automatically compile and wrap a dts file from arch/powerpc/boot/dts into the zImage file. The resulting zImage will be arch/powerpc/boot/zImage.dts.<platform> and arch/powerpc/boot/zImage.dts_initrd.<platform>, respectively. Having separate rules allows the user to choose whether to include a device tree--and which device tree--at build time. This is useful when one Makefile target builds a zImage that runs on several platforms except for differing device trees. By just setting CONFIG_DEVICE_TREE and running "make zImage.dts" the exact zImage you want is built without Makefile bloat or manually running the wrapper script. The dts file is expected to be arch/powerpc/boot/dts/$(CONFIG_DEVICE_TREE) Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-05-12[POWERPC] U-boot passes the initrd as start/end, not start/size.Scott Wood
The boot wrapper platform init code on 83xx and 85xx using the cuboot platform type was incorrectly assuming that u-boot supplied the size of the initrd, whereas it actually supplies the end address. This fixes it. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
